The Provisions of the Landmark 2010 U.S. Health Care Reform Legislation , After decades of discussion and sometimes venomous disagreements and a year of rancorous and polarizing debate, both in Washington and across the United States, the U.S. Congress narrowly enacted the Patient Protection and Affordable Care Act, the most far-reaching health care reform since the passage of Medicare in 1965. The measure, which was followed by a separately signed reconciliation package, was a centrepiece of Pres. Barack Obama’s domestic agenda, but passage of the 2,074-page bill did not come easily.

Soon after his inauguration in early 2009, President Obama called for quick action by Congress, citing a century of failed health care reform efforts. He did not spell out a plan of his own but instead left that to the lawmakers. What ensued was a wrenching roller-coaster ride during which Congress held virtually nonstop debates, local town-hall meetings rang with acrimony, and five congressional committees passed three separate versions of comprehensive reform. In March 2010, just as the historic measure teetered on the brink of defeat, Obama and Democratic leaders, notably Majority Leader Harry Reid in the Senate and Speaker of the House of Representatives Nancy Pelosi, mounted an all-out last-ditch campaign, followed by legislative maneuvering that resulted in passage of reform without the support of a single Republican member of Congress.

The final legislation would extend coverage to some 32 million additional Americans by 2019, leaving about 6% of legal residents uninsured, according to the Congressional Budget Office (CBO). The overhaul would require most individuals to secure health insurance or pay fines, make coverage easier and less costly to obtain, crack down on abusive practices of insurers, and, its backers hoped, start to rein in the relentless rise of health care costs. It did not, however, create what many advocates had wanted most—a single-payer system or a federal government-run insurance option. Instead, there would be new state-run health insurance marketplaces called exchanges.

The CBO estimated that the plan would cost $938 billion over the next 10 years but would reduce the budget deficit by $143 billion in that period and by another $1.2 trillion over the following decade. The sweeping changes would be paid for primarily by savings in Medicare, new approaches to health care generally, and new taxes on wealthy Americans and on high-priced workplace insurance policies.

While some provisions of the new law would not take full effect for several years, many began in 2010. These included:

Insurance plans no longer were able to deny coverage of preexisting conditions in children, nor could insurance providers put a lifetime limit on payouts. People who were uninsured because of preexisting conditions could get insurance through a temporary high-risk pool.

Within six months of the bill’s signing, all existing health plans and any new ones were required to cover dependent children of policyholders until age 26.

The “doughnut hole” gap in Medicare coverage for prescription drugs would start to be closed and would be entirely wiped out by 2020. Medicare recipients who reached the gap in 2010 would receive a $250 rebate, and seniors were promised discounts on brand-name drugs in future years.

Private insurance plans were required to offer minimum packages of benefits that would be determined by the federal government.

Several additional changes were slated to phase in starting in 2014, including:

Most Americans would be required to have a minimum level of health insurance or pay a penalty starting at $95 a year. Individuals and households below the tax-filing threshold would be among those exempt.

By 2014 states would have to create health insurance exchanges that would be open to people who did not have coverage through their job and to employers with 100 or fewer workers. To help low- and middle-income Americans (those with annual incomes up to $43,320 for individuals and $88,200 for a family of four) buy insurance at exchanges, the government would provide tax credits for premiums and out-of-pocket costs.

An estimated 16 million uninsured people would become eligible for Medicaid, the federal-state program for the poor. This included anyone earning less than 133% of the poverty level ($29,327 a year for a family of four). From 2014 to 2016, as this provision took effect, the federal government would foot the entire bill for newly insured recipients, but the federal share would gradually decrease to about 90%. Washington paid an average of 57% of Medicaid costs in 2009.

Although businesses would not absolutely have to offer health insurance to employees, those with 50 or more workers would be assessed a penalty starting in 2014 if they did not offer benefits and if any of their workers bought subsidized coverage through the new exchanges.

Two controversial limitations were imposed on the use of federal money under the reform law. Federal funds could not be used for abortions except in the case of rape or incest or if the life of the pregnant woman was in danger. Meanwhile, illegal immigrants would not be able to buy insurance from subsidized exchanges even if they paid the full cost themselves.

To finance the health care overhaul, several new fees and taxes would be levied. An excise tax would be imposed on the most expensive employer-sponsored health insurance plans (those with premiums costing more than $10,200 for individuals and $27,500 for families). Beginning in 2013, the Medicare payroll tax would be increased from 1.45% to 2.35% for high-salaried employees, who also would have to pay a new 3.8% tax on unearned income, including stock dividends and capital gains.

Meanwhile, the reform sought to start reducing health care costs by rewarding doctors for keeping patients healthy rather than just treating them when they became sick. Other provisions were designed to cut expenditures by encouraging money-saving innovations in Medicare and by reducing some Medicare benefits, especially those paid by government-subsidized private Medicare Advantage plans.
